Hibiki's answer to EVERYTHING is Vash
Lets see what I can come up with
It's been so long since I've read the play
Vash wouldn't make a bad Romeo. He does both the direly serious emotional stuff as well as the more light hearted half joking stuff (IE Romeo's encounter with Tybalt before he ends up killing him
)
Friar Lawrence. Well, need to come up with a figure thats like a guide, father figure type. Washi (Haibane renmei) would work well as would a character like the temple priest from X.
This might be kinda cheating but Seifer (FF8) would make a badass Tybalt. He's got the ego, the inferiority complex, the violent attitude, everything really.
Hmmmmm, mercutio. Something of a neutral character who ends up falling on romeo's side more often than not yet still finds the whole feud to be foolish. He just seems to want to have fun a lot of times. Akito from Nadesico.
Don't remember jack about benvolio's character.
The nurse. A figure who cares more for Juliet than for herself and acts as a surrogate mother. Another bit of s stretch just because this character has much more to her than just this, but Reki from Haibane renmei would work out.
And Juliet...I got no clue.
